STEAM-TURBINE-DBIVEN VEHICLE.

Application filed December 22. 1915).

To all whom 'il muy romero.'

Switzerland, have invented eertain new and iif-:el'nl lniprovenients in Ste-.iin-Tiirbine- Driven Velin-les; and l. do hereby deelare the Jfollowing to be a elear. full. and exact description of the invention. anch as will enable others skilled in the art to whiffli it apport-aim` to iiiake and use the saine. referein-e being had io the aeeoiiip-.iiivliig drawing. and to lettera` or ligure-s; ol' reference marked thereon. wliieh 'forni a part of' thi@y aiawilicatioii.

rl`he invention relates# to steanir-larbiiie driven \'eliiele, in wliif'li the siriani-turbine traii mitsy its1 power in a manner well known with electrical drives bv ineans oi a doable spur-gearing to a blind shaft, and the latter transmite` the power by means of a crank gear to al least one driving axle. lith this arraiigenient sieaiii -tiirbiiie and transmission gear niay for the iiiosi parl be placed below the boiler.

Vith the heretofore known steam-turbine driven vehicles the turbine. traiisiiiilitod its power either direetl)l by mean.: of beveb wheels onto the driving-axle. or by 'means of bevel-wheela` to a iongitiidiiiall;1 arranged shaft and troni the latter again hv ineaiie` of lnivelfwlieelhv to a driving axle. Thisl trananiisaion olf power has the great disadvantage that bevel-wheels are not suited for transmitting large powers when running :it high speeds. VFurther it in difficult to construe( bevel wheels wliieli engage well. Thejvv produce great noise.A are subjettetl lo inneh wear and eanse a eonenlerable axial thrust. These disadvantages are overeo by the present invention. It 'is not with vehicles driven by eleetro-niotorr, to arrange the latter transversely to the direi tion ol" ruiming and to canse tliein to drive b v means of spur-gearing onto the drivingaxleS.

These machines-i, however. are no power prodiieiiig engines. they are dependent on a iviationary priiiiary power station and oiia transiiiisaion line. ln opporsition to that arrangement. the required working A power may be produced on the Stiainrloeoinotive proper and in spite of certain :.idvant-.iges ol' the electricy drive, the constructors have invariablyv fallen back on the steam-drive, endeavoriiig to increase t-lie economy in Specication of Letters Patent,

'l`he earrviiig into ellri'l oll thin invention allowa ol' riniiiing the ini-bine at a ver high apeed. l'lereblv lhe runner-l)lading is anhjerted to a laioi'able virrnnit'eiential rained whih` keeping the de ii-ed Sinall dianieieix and a anilable ratio between the leain and the rirvonilereiiiial veioeiiies is attained.

2. A steam-turbine driven vehicle, coinprising a turbine, a blind Shaft, two spurgear Systems operatively connecting the tur bine and the blind shaft, and crank gear operatively connecting the blind shaft and the driving axles of the vehicle.

3. A steanrturbine driven vehicle, coniprising a turbine and a transmission gear for transmitting the power of the turbine to tbe drivingr axles colinisting,r ot two spurgear systems, a blind-shaft and eranli gear, the steam-turbine and the transmission gear boing for the most part` arranged below the boiler.

4. A steam turbine driven vehicle comln'ising a boiler, a turbine supplied from said boiler and a surface condenser into wliiob said turbine discharges, a blind shaft, Lransniisoion spar gearing between said turoine and blind shaft and a crank mechanism operated by said blind shaft for actuating tbc several driving wheels of the vehicle.
